Starch is an inexpensive commodity that has been used for non-food purposes for many years. Some of these uses include cross-linked starches that are synthesized with a variety of multifunctional reagents. One unexplored possibility is the use of azides for cross-linking. To this end, azide derivatives of different starches have been synthesized, including the first reported synthesis of 6-deoxy-6-azido-amylopectin. Lithium salts, which were found to not be essential for the dissolution of starch in the reaction, were replaced with sodium azide. The time for this derivatization reaction to reach completion was determined to be 1 h. N,N-dimethylacetamide was also found to be a suitable solvent. Initial experiments suggest that the azide derivative does cross-link starch when activated by heat.
